DAVID H. YOUNG; or MANCHESTER, NEWHAMPSHIRE.

Letters Patent N 90,550, dated October 5, 1869.

IMPROVEMENT IN EURNAcE-noo FRAMES.

The Schedule referred toin these Letters Patent and making part of the same.

To livhomit may concern:

Be it known that I, DAVID H. YOUNG, of Manchester, county of Hillsborough, and State of New Hemp shire, have invented certain Improvements in Furnace- Door Frames; and do hereby declare the following to be a full, clear, and exact description thereoti'reference being had to the accompanying drawings, in which- Figure 1 represents a front view of my improved frame.

Figure 2\ is a side view, showing top-flange.

Figure 3 is a planrv'iew, showing side-flanges.

The object of my invention is to produce a frame for furnace-doors which can be held tightly in the masonry, without the liability of becoming loose; 'this is secured by flanges upon three sides ofthe box of the `frame; and to so construct .the face ot' the frame that the door may be easily adjusted lso as to s\ving eitl1er way.

The nature oi' my invention consists in the box` hav-V ing flanges upon three sides of' the same, which hold upon the masonry in such a manner that the box will not become loose; and

i The nature of the invention consists, further, in constructing the hinges of the door in such a mnnner that the door can be adjusted to open either-way.

In the drawings- A is the face ot' thedoor-fralne, and is .provided with a. double set'cf hinge-ears, E E and E' E', that is, one set upon each side, and latches L and L', one upon each side. l

B is the door.

D, the box, around which masonry is built.

The. inner face of'tbis boxjs provided with flanges, l, F', and F". These 'are upon the upperpart and eaclrside. Heretofore, a flange has been put only on one part.

The advantages of my improved furnace-door frame are, that the door can open either way, without taking out the door-frame and reversing it, as is the present method of accomplishing this result-,and the security against the loosening of the frame in the work around it, the flanges described eiertuully preventing the box from becoming loose.

What I claim,'thereiore, :is my invention, and desire to secure by Letters Patent, is

1. The device A, having hinge-ears 1*] E and E' E', and latches L and L', for the face ot' :i furnace-door frame, substantially :is described.

2. The box D, having ianges F, F', and F", as an improved setting-box to a furnace-door frame, substantially as set forth.

3 The combination oi' box D, constructed vas described, and face A, constructed as shown, 'substan-V tially as set forth. l

The above speciiication of my invention signed by me, this 4th-day of June, A. D. 1865).
